Antminer D3 Blissz firmware (10/12 v1.12 update)

[ruptan]

Settings Per Chain (will override the global settings when set)

Chain 1:
Frequency:556M
ASIC Voltage:13

Chain 2:
Frequency:556M
ASIC Voltage:12

Chain 3:
Frequency:556M
ASIC Voltage:11

Result:

19,536.7 MHS
1225 WATTS

30 mins runing 0 HW.

Nice performance setting. Maybe you can lower the voltage a step on all the boards. It's ok to have a few HW errors every hour.

Hi,
I uploaded your file and getting hard Untar error while doing the Flash image. Do you know why? I have this one that I downloaded from your link.

Don't unpack anything before flashing it. Just flash the downloaded file

The D3 cgminer driver (released by Bitmain) doesn't even mention X11 or subalgorithms. You can check:

• https://github.com/bitmaintech/cgminer-dash/blob/master/driver-btm-DASH.c
• https://github.com/bitmaintech/cgminer-dash/blob/master/driver-btm-DASH.h

There is struct work_dash that contains interesting type field. However it has fixed unknown value 0x20.

Code:

    
struct work_dash
{
    uint8_t type;                           // Bit[7:5]: Type,fixed as 0x01. Bit[4]:sno valid   Bit[3:0]:reserved
    uint8_t wc;                             // bit[7]: reserved, bit[6:0]: work count base
    uint8_t work[WORK_DATA_INPUT_LENGTH];   // 0-75 bytes are dash work; 76-79 are start nonce field
    uint16_t crc16;                         // crc, but not include the header 0x55, 0xaa
};
//...

// BM1760 ASIC input data length
#define WORK_INPUT_TYPE_WITH_SNO                    0x30
#define WORK_INPUT_TYPE_WITHOUT_SNO                 0x20

//...

void *DASH_fill_work(void *usrdata)
{
struct work_dash workdata;
//...
workdata.type = WORK_INPUT_TYPE_WITHOUT_SNO;
//...
DASH_write(info->dev_fd[chainid], (uint8_t *)&workdata, WORK_INPUT_LENGTH_WITH_CRC);

It would be interesting to fuzz work_dash.type a bit, to see if BM1760 supports some other types. However probably this wouldn't do anything useful.

So IMHO this means unless there is secret golden switch inside chip BM1760, there is no way to choose algorithm.
BM1760 is Bitmain private chip. There is no public spec available, all they say about it is "BM1760 custom-made chip using 28nm technology."  

thank you for infos!
I think we are close to the end of the discussion about mining other algos!

Where is Xhash() function defined ? It has called from driver-btm-DASH.c but i could not see anywhere that the function decribed declared ..

any idea about Xhash function ?

21/11 recommended UPDATE

https://mega.nz/#!flAF1R5Z!Y8PYNimTXv7gt3xzKEf6LKHOoVxNEoaybKC4B9vyyzk

Changes 21/11:
- Firmware now based on latest Bitmain firmware (20/11/2017)
- made default bitmain voltage a bit more clear in the list.
- Applied a more silent AUTO fan profile.
- Fixed the high fan RPM at startup when using AUTO fan speed
- several webinterface fixes


know issues:
- switching pools can sometimes cause the miner to wait for work for 10 seconds.

happy mining!

getting quite a few HWs on chain one on one of my D3's.

Global Clock is set to 400MHz

Time on: 53 minutes

Chain 1: 25 (Voltage set to 3)
Chain 2: 0 (voltage set to Global LOWEST)
Chain 3: 0 (voltage set to Global LOWEST)

i've bumped the voltage three times now and i'm wondering if perhaps this chain didn't win the lotto.

I've read 10 HW per hour is acceptable. Is that per chain, or a total of all chains per hour?

Per chain

[crackfoo]

Right now my D3 is set at:

456mhz
1 voltage

and draws 840-850watts @ 16.4Gh

chip temps ~65-70

4 hw errors after 4 hours.

Great result I would say!

[Knightslugger]

Per chain

Am I on the right track as far as getting rid of these HW errors by increasing chain voltage?

[fecell]

So if there is one place where it may be possible to trigger single algo mining, it would be inside the PIC.

Firmware PIC from D3 and from L3+ identical.

[fecell]

anyone can read and post content of the PIC?

PIC firmware (microcode) stored in \sbin\pic.txt in D3 firmware.

@Blissz, I am a hardware/firmware developer. I got the wild notion to inspect the processor board and found it to be a Beaglebone_black_v2.3, my version anyway. I went to Beaglebone.org and found the specs. This D3 version is missing some crucial parts like the usb, buttons and some other chips.
Here are links:
https://elinux.org/Beagleboard:BeagleBoneBlack#BeagleBone_Black_Description
https://www.dropbox.com/s/g6m02oyr0gl3tbt/AntMinerD3-IMAG1305.jpg?dl=0
https://www.dropbox.com/s/xo6zhz8irfq1mg8/AntMinerD3-IMAG1307.jpg?dl=0

Now here is the internet bomb:
We all know or should that there are threads about the D3 explaining Bitmain's use of the D3 to corrupt the market against any competition. Whether this is true or not it stands to reason that the greedy operate this way. So I gave it some thought and here goes:
How could BM impact the market quickly and most efficiently? Simple repackage an existing product and the clamor of the market would make the necessary statements to promote the 'NEW' product which the public did. In this case BM didn't have to lift a finger because of the trust and product effectiveness that the S series products had gained in the market. The trap is set.
How did BM get the D3 to market? We look at the runtime specs. Fans are loud, the hashing advertisement is high for x11, the speed is high. But the overall performance / profitability is negative in most cases. Any country that has high utility prices is not a great home for these units. My suspicion is these are S9s or lower and reconfigured for x11 with a conversion routine. And why not? Nicehash, Zpool, and Prohash do it! Right?
Repurposed S7s or lower would make the best sense. Keep making lower hashrate boards and plug and play. Who would know? With the conversion the high hashrate BTC boards would easily perform the task AT THE COIN RATES THAT EXISTED AT THAT TIME. They don't perform at the time of this writing but as I said 'THE TRAP WAS SET' and purchasers are screwed, the competition is dead and the market has consumed up any single unit purchasers from ever continuing.

Two things pertaining to the hardware. I have a D3 off grid right now and an S9 on grid that I will be moving in a couple of days so I will have a look at the hash cards for similarities.
After that, if I notice that the boards are the same I will order a Beaglebone black from Beaglebone, flash and MSD image, install and try it. It cant hurt. If this works then this will be a start at opening the platform.

There is a thread about one of the developers modifying the Bitmain software but he has since disappeared.

I am open to any thought on this...

Chip on l3+ ---> BM1485
Chip on d3 ----> BM1760
Chip on S9 ----> BM1387
you are not the first one who does this, and apparently you do not understand how it is arranged
IMHO

Yeah, so what? A slam is the correct response besides the initial table list? Don't be a rude noob. Take note as to other paths on this thread:

If you know something, great! You don't have to crucify with it.

[MantaMine]

Seems to be some instability caused when using manual mode for fans.  Chips were running a bit warm so upped to speed and started getting HW errors.  Anyone else seeing this?

I updated the firmware using the link in page 31 (21/11 recommended UPDATE) and set the following

Fan percentage to 30%

Global settings
Frequency: 431M
Asic volatge: lowest

Chain 1
Frequency: 462M
Asic volatge: 1

Chain 2
Frequency: Use global
Asic volatge: Use global

Chain 3
Frequency: 425M
Asic volatge: 1

Been running for about 1hr and I have a HW 5 in chain 1 with discarded 2,177 on my main pool. Is this normal? What's the meaning of HW 5 and discarded? I'm new on using an asic miner.

Something's wrong with your pool, i wouldn't suggest you use zpool, not reliable, i still remember that 20% hidden fees, use granatgas-pool instead.

[hta]

Bitmain has new firmware for D3. Just in case you n Ed to know this for the new

Firmware mods you tweak.

Yes, the new firmware on 11/20, Blissz should check.

1. fix the issue: some miner's chip status is 'x' after running for several hours or days.

Of S9

Thanks, I'll switch to granatgas-pool. It seems https://granatgas-pool.info/ is down.

Also, blizz - thank you for putting in the work on this.  1.5% fee is definitely reasonable for what you've provided.  Look forward to watching this evolve.
